Description

  The present invention relates to a projected corner column printing apparatus and a projected corner column printing method for printing a chamfered portion of a projected corner column to be constructed at a projected corner portion of a building outer wall, and in particular, a projected corner column printing method in harmony with a highly designed outer wall plate. The present invention relates to a projected corner column printing apparatus and a projected corner column printing method capable of performing printing of a corner column chamfered portion with a simple operation.

  1A and 1B are a perspective view and a cross-sectional view showing a structure of a protruding corner column. The protruding corner column has a structure in which the protruding corner column left piece 11 and the protruding corner column right piece 12 are joined to each other substantially at right angles. When building a corner column of a building, a material of the same quality as an outer wall plate (for example, a ceramic industry outer wall plate) arranged on both sides of the exterior design is often used. In contrast to the horizontal construction of ceramic-type outer wall panels, the projecting corners are formed by joining the projecting corner pillars (see FIG. 1) having the same vertical dimension of the outer wall panels constructed on the left and right sides in the vertical direction. The outer surface has a convex portion 13 and a concave portion 14 in order to maintain continuity with the general-purpose block pattern of the left and right outer wall plates, and has a chamfered portion 15 in front of the corner portion.

  And the outer wall of the building exterior corner part is constructed | assembled by adhere | attaching the outer wall board constructed in right and left, and each piece 11 and 12 which comprises an exterior corner pillar, and fixing with the tucker 19. FIG. More specifically, a hat joiner (see Patent Document 1 or the like) is used to keep the distance between each of the protruding corner pillars 11 and 12 and the outer wall plates arranged on the left and right sides in order to complete the rain. The sealing material is placed on the top surface of the hat joiner, but since these configurations are not directly related to the present invention, detailed description thereof is omitted.

  For each piece 11, 12, the same material as the outer wall plate is cut into a predetermined size and used, so that the lower solid portion 16 is already formed on the upper side portion and the upper solid portion 17 is formed on the lower side portion, The joining in the vertical direction can be done by joint joining. In addition, since the caulking material 18 has already been placed in the lower solid portion 16, it is possible to prevent rainwater from entering from the joint gap portion between the protruding corner columns arranged above and below.

  FIG. 2 is a diagram for explaining a method of manufacturing a protruding corner column. Using the outer wall plate 1 having a thickness h, the projected corner constituting materials 1a and 1a are cut out from the outer wall plate 1 with a lateral width a (FIG. 2 (a)). Then, one side of each is cut to a predetermined angle to form taper cut portions 2 and 2 (FIG. 2 (b)), and the taper cut portions 2 are bonded together and stopped with a tacker 19 as required (FIG. 2 ( c)), integrated into an angle-invariant state (FIG. 2 (d)). Here, when the left and right protruding corner constituent materials 1a and 1a are joined at approximately 90 degrees, there is a possibility that the constituent materials 1a and 1a are slightly shifted on the joining surface. In addition, the adhesive may protrude from the surface. In consideration of the occurrence of such defects, the chamfered portion (1) 5 is formed by cutting in consideration of the appearance of the protruding corner (FIG. 2 (e)). Similarly, the chamfered portion (2) 6 may be cut and formed from the aspect of improving the appearance.

  About this chamfered part, since the cement base material which is an outer wall board material will be exposed, waterproofness will be impaired naturally. Therefore, repair painting is performed later. In many cases, brushing or roller coating is performed manually, but the applicant of the present application has proposed mechanization (see Patent Document 2).

  In addition, although application | coating of an adhesive agent is often performed manually, this applicant has proposed mechanization (refer patent document 3). In addition, a jig is used to maintain the angle formed by the two protruding corner constituting members 1a and 1a at approximately 90 degrees (see Patent Document 4).

  FIG. 3 is a diagram for explaining a position where the protruding corner constituent material is cut. When the outer wall plate 1 (surface painted) used as a material is cut into a number of protruding corner constituent materials 1a in the short direction (step of FIG. 2 (a)), each of the two adjacent protruding corner constituent materials 1a Since the handle pattern needs to be continuous at the joint, it is necessary to consider the cutting position of the material plate. For example, in the case of a pattern such as a brick pile (consisting of a large number of convex 21 flat design surfaces and surrounding concave portions 22), avoid vertical joints of the concave portions 22 as shown in FIG. Cut at the position S.

  FIG. 4 is a diagram for explaining a joint portion of the protruding corner column. By cutting at the position shown in FIG. 3, the convex pattern butt joint portion 31 of the protruding corner column can be continued in each of the left and right components 1a and 1a. At that time, with respect to the groove portion (concave portion 22), the front end portions (cutting positions) of the left and right constituent members 1a and 1a are abutted and joined as a concave portion abutting joint portion 32.

FIG. 5 is a diagram for explaining chamfering. In the chamfering process, if a chamfering machine that uses the feed roller 42 to convey the protruding corner column and can move the air grinder 41 up and down is used, the convex pattern butt joint 31 and the concave butt joint 32 are used. Can be chamfered together, and a chamfered portion having continuous steps is formed.

  The chamfered portion (1) 5 shown in FIG. 2 is a portion that becomes the corner of the protruding corner column and is a conspicuous portion. If the design of the outer wall plate arranged on the left and right is something like a mono color, it will not be a problem if you apply the same color or similar color paint (brush coating or roller coating), but the outer wall plate As the design of the material becomes higher, there is a risk that it may cause a sense of incongruity when painting with a single color.

  In view of the above-described problems, the present invention provides a projected corner column printing apparatus and a projected corner column printing method capable of performing printing of a projected corner chamfered portion in harmony with a highly designed outer wall plate by a simple operation. The purpose is to do.

The projected corner pillar printing apparatus according to the present invention photographs the chamfered portion of the projected corner column and its periphery conveyed by the conveying means for conveying the projected corner column with the chamfered portion in front of the projected corner column facing upward. camera and a contour information acquisition means for acquiring location information of the contour of the chamfered portion from an image taken by the camera, next to the region surrounded by the contour obtained by the edge information obtaining means and the external corner pillar which It includes a contour processing means to enlarge the contour in the enlarged direction, and a chamfer printing means for printing a region surrounded by the enlarged contours in the chamfered portion of the external corner pillar front.

Further, from the image photographed by the camera, obtain a preprinted image of the convex portion of the brick-laying pattern composed of a large number of convex portions and concave portions around the convex portion around the chamfered portion, The image forming apparatus further includes a convex image creating unit that enlarges an already-printed image in the vertical direction of the protruding corner column to form a printed image of the convex portion of the chamfered portion, and the chamfered portion printing unit is created by the convex image creating unit. By printing the printed image on the convex part of the chamfered part, the image will be slightly different from the original pre-printed image. A printed image that relaxes and absorbs the appearance can be finished.

Also, external corner pillars printing method of the present invention, the transport step and the chamfered portion and around the external corner pillar carried by conveying step of conveying the external corner pillar in the upper chamfered portion of external corner pillar front A photographing step for photographing the contour, a contour information obtaining step for obtaining position information of the contour of the chamfered part from an image photographed by the photographing step, and a region surrounded by the contour obtained by the contour information obtaining step. A contour processing step that expands in the lateral direction of the corner pillar to form an enlarged contour, and a chamfered portion printing step that prints a region surrounded by the enlarged contour in the chamfered portion in front of the projected corner pillar .

  ADVANTAGE OF THE INVENTION According to this invention, printing of the corner-corner chamfering part in harmony with the outer wall board with high designability can be performed by simple operation.

  The best mode for carrying out the present invention will be described below in detail with reference to the accompanying drawings.

  FIG. 6 is a diagram showing the configuration of a projected corner post printing apparatus according to an embodiment of the present invention, and FIG. 7 is a flowchart for explaining the operation thereof. The present corner pillar printing apparatus includes a conveyor 51, a digital camera 52, a plate tip detector 53, a printing head A 54, a heating fixing zone 55, a printing head B 56, and a chamfer printing controller 61. The chamfered portion print controller 61 includes a conveyance control unit 62, a print control data creation unit 63, a print head A control unit 64, and a print head B control unit 65.

  First, the transport conveyor 51 is controlled by the transport control unit 62 to transport the protruding corner column 71 with the chamfered portion 72 facing upward, and the digital camera 52 shoots the periphery including the chamfered portion 72 of the protruding corner column 71. Then, the image signal is sent to the print control data creation unit 63 (step S1). The digital camera 52 may shoot a moving image, but it is sufficient to shoot a still image. In particular, when a general-purpose product is to be used, a camera that captures a still image is preferable because it has a higher resolution. When shooting with a still image camera, the entire projected corner column 71 may be captured, but since the projected corner column 71 is long, the projected corner column 71 is divided into several parts and shot. You may synthesize.

  FIG. 8 is a top view and a cross-sectional view showing a part of the chamfered portion. The upper side of the figure is a top view and the lower side is a cross-sectional view with the left side of the figure as the upper end of the protruding corner column. As shown in FIG. 5, the cutting process is performed by the vertical movement of the air grinder 41 along with the conveyance of the protruding corner column, so that a smooth inclined curved surface is formed in the concave portion in the chamfered portion 72.

  From the upper end of the protruding corner column, ascending curved surface (3) → upper chamfered flat surface (4) → descending inclined curved surface (5) → low chamfered flat surface (6) → rising inclined curved surface (7) As the surface (4) 'comes, a continuous printing surface with undulations is formed by chamfering. On both sides thereof, there are a ground color preprinted surface PU (in this case, both sides are plain), a left preprinted surface PL, and a right preprinted surface PR of the painted outer wall plate 1. These left preprinted surface PL and right preprinted surface PR have patterns on the convex portions peculiar to the block pattern.

FIG. 9 is a diagram illustrating a captured image of the chamfered portion. The x-axis is the direction in which the projected corner column 71 is transported, and since the projected corner column 71 is transported while the digital camera 52 is stationary, it is also a time axis. Since the x-axis direction is the vertical direction after construction, it is referred to as the vertical direction of the protruding corner column. The y axis is a direction orthogonal to the x axis. Since the y-axis direction is the horizontal direction after construction, it is referred to as the lateral direction of the protruding corner column. The print control data creating unit 63 acquires the position information of the contour of the chamfered part 72 from the image signal obtained by photographing the chamfered corner post with the digital camera 52 (step S2). Since the chamfered portion 72 is in a state in which the ground of the coated outer wall plate 1 is exposed by cutting, at least one of the hue, saturation, and brightness of the image signal is different from the surrounding printed surface. Therefore, the position information of the contour of the chamfer 72 can be acquired from the image signal obtained by photographing with the digital camera 52. Both the upper contour line CO and the lower contour line CU obtained almost symmetrically with the chamfered portion center line CL as a center are in a jagged state as a result of cutting.

  The print control data creation unit 63 further enlarges the print area by a few print dots in the y-axis direction so as to cover the acquired jagged outline (step S3). By doing so, the pattern transfer from the left printed surface PL and the right printed surface PR to the chamfered portion 72 is less noticeable. At this time, printing is performed by slightly protruding from the chamfered portion 72 to the left printed surface PL and the right printed surface PR, but it is made inconspicuous.

  Next, the print control data creation unit 63 creates color data. The upper chamfered flat surfaces (4), (4) ′,... Shown in FIG. 8, the rising inclined curved surface (3), the falling inclined curved surface (5), the lower chamfered flat surface (6), the rising inclined curved surface ( 7), ..., and the parts (3), (5), (6), (7), ... about the ground color printed surface PU obtained from the digital camera 52 The color data (RGB (Red Green Blue) data) is used as the color data for printing the background portion. The portions (4), (4) ′,... Are portions that are connected printing surfaces of the left printed surface PL and the right printed surface PR.

  FIG. 10 is a diagram for explaining a process of creating a linked print image. The image PLm and the image PRm on the left printed surface PL and the right printed surface PR of the portion corresponding to the width m + m of the chamfered portion 72 are combined to obtain color data of the composite image. Further, the composite image is enlarged by several printing dots in the x-axis direction (step S4). The color data (RGB data) for the enlarged composite image is used as the convex connection printing color data.

  By doing so, the connected printing surface (4) is printed slightly protruding on the surfaces (3) and (5) continuous in the x-axis direction, but it is hardly noticeable. . By expanding the composite image on the connected print surface in the x-axis direction, an image that is unavoidable at the joint portion of the composite image is formed by making the image slightly different from the original left printed surface PL and the right printed surface PR. The printed image is finished to absorb the occurrence of the appearance as a whole.

The color data for printing the base portion and the color data for connecting the convex portions are converted into CMYK (Cyan
Magenta Yellow BlacK) is converted into color data and converted into ink ejection control data (printing control data) of individual nozzles constituting each color nozzle array.

  Further, the printing start position is determined according to the amount of protruding printing in the x-axis direction. The printing head A 54 is controlled by the printing head A control unit 64 and counts pulses generated at a predetermined frequency from the time when the leading end of the protruding corner column 71 is detected by the plate leading end detector 53 by a predetermined number of pulses. Thus, printing of the entire surface of the chamfered portion is started with the color data for base portion printing (step S5). This is because, in addition to the formation of the print base, it also serves to ensure the waterproof property of the exposed surface of the substrate. Therefore, printing is performed with a larger amount of ink than in the case of normal coloring. In addition, since the concave groove color is usually a single color, the influence of the distance difference between the inclined surface and the nozzle is hardly noticeable.

  The heat fixing zone 55 heats and fixes the base color ink after the entire surface of the chamfered portion is printed by the printing head A54.

  The print head B56 is controlled by the printhead B control unit 65, and counts a predetermined number of pulses from the time point when the tip end of the protruding corner column 71 is detected by the plate tip detector 53, whereby the upper chamfered flat surface ( The printing of the portions 4), (4) ′,... Is started by the convex connecting color data generated by the printing control data generating unit 63 (step S6). Then, printing is performed until the entire surface of the chamfered portion is printed.

  For printing in the x-axis direction, since the printing resolution is determined by the ink ejection frequency of the nozzle and the traveling speed of the protruding corner column, the ink ejection frequency of the nozzle and the traveling speed of the protruding corner column are determined according to the required printing resolution. It is done. From the standpoint of productivity, it is not necessary to run the protruding corner column at a higher speed than when printing the outer wall plate because it is not necessary to produce as many as the outer wall plate. Therefore, in the entire surface printing of the chamfered portion, it is possible to execute the printing without worrying about the change in the printing distance of the inclined surface portion caused by the traveling of the protruding corner column that is the printing object.

  In addition, this invention is not limited to the said Example.

  It goes without saying that the present invention is also realized as a protruding corner column printing method.
